It does not require you to mount -the image file to copy files on it, nor does it require that -you become the superuser to make device nodes. - -The filesystem image is created in the file \fIoutput-image\fP. If not -specified, it is sent to stdout. - -By default, the maximum number of inodes in the filesystem is the minimum -number required to accommodate the initial contents. -In this way, a minimal filesystem (typically read-only) can be created with -minimal free inodes. -If required, free inodes can be added by passing the relevant options. -The filesystem image size in blocks can be minimised by trial and error. -.SH OPTIONS -.TP -.BI "\-x, \-\-starting\-image image" -Use this image as a starting point. -.TP -.BI "\-d, \-\-root directory[:path]" -Add the given directory and contents at a particular path (by default -the root). -.TP -.BI "\-D, \-\-devtable spec\-file[:path]" -Use \fBspec-file\fP to specify inodes to be added, at the given -path (by default the root), including files, directories and -special files like devices. -If the specified files are already present in the image, their -ownership and permission modes will be adjusted accordingly. -Furthermore, you can use a single table entry to create many devices -with a range of minor numbers (see examples below). -All specified inodes receive the mtime of \fBspec-file\fP itself. -.TP -.BI "\-b, \-\-size\-in\-blocks blocks" -Size of the image in blocks. -.TP -.BI "\-N, \-\-number\-of\-inodes inodes" -Maximum number of inodes. -.TP -.BI "\-i, \-\-bytes\-per\-inode ratio" -Used to calculate the maximum number of inodes from the available blocks. -.TP -.BI "\-m, \-\-reserved\-percentage" -Number of reserved blocks as a percentage of size. Reserving 0 blocks will prevent creation of the "lost+found" directory. -.TP -.BI "\-g, \-\-block\-map path" -Generate a block map file for this path. -.TP -.BI "\-e, \-\-fill\-value value" -Fill unallocated blocks with value. -.TP -.BI "\-z, \-\-allow\-holes" -Make files with holes. -.TP -.BI "\-f, \-\-faketime" -Use a timestamp of 0 for inode and filesystem creation, instead of the present. Useful for testing. -.TP -.BI "\-q, \-\-squash" -Squash permissions and owners (same as -P -U). -.TP -.BI "\-U, \-\-squash\-uids" -Squash ownership of inodes added using the -d option, making them all -owned by root:root. -.TP -.BI "\-P, \-\-squash\-perms" -Squash permissions of inodes added using the -d option. Analogous to -"umask 077". -.TP -.BI "\-v, \-\-verbose" -Print resulting filesystem structure. -.TP -.BI "\-V, \-\-version" -Print genext2fs version. -.TP -.BI "\-h, \-\-help" -Display help. -.SH EXAMPLES - -.EX -.B -genext2fs -b 1440 -d src /dev/fd0 -.EE - -All files in the -.I src -directory will be written to -.B /dev/fd0 -as a new ext2 filesystem image. You can then mount the floppy as -usual. - -.EX -.B -genext2fs -b 1024 -d src -D device_table.txt flashdisk.img -.EE - -This example builds a filesystem from all the files in -.I src, -then device nodes are created based on the contents of the file -.I device_table.txt. -Entries in the device table take the form of: - -<name> <type> <mode> <uid> <gid> <major> <minor> <start> <inc> <count> - -where name is the file name and type can be one of: -.RS -.nf -f A regular file -d Directory -c Character special device file -b Block special device file -p Fifo (named pipe) -.fi -.RE -uid is the user id for the target file, gid is the group id for the -target file. The rest of the entries (major, minor, etc) apply only -to device special files. - -An example device file follows: - -.RS -.nf -# name type mode uid gid major minor start inc count - -/dev d 755 0 0 - - - - - -/dev/mem c 640 0 0 1 1 0 0 - -/dev/tty c 666 0 0 5 0 0 0 - -/dev/tty c 666 0 0 4 0 0 1 6 -/dev/loop b 640 0 0 7 0 0 1 2 -/dev/hda b 640 0 0 3 0 0 0 - -/dev/hda b 640 0 0 3 1 1 1 16 -/dev/log s 666 0 0 - - - - - -.fi -.RE - -This device table creates the /dev directory, a character device -node /dev/mem (major 1, minor 1), and also creates /dev/tty, -/dev/tty[0-5], /dev/loop[0-1], /dev/hda, /dev/hda1 to /dev/hda15 and -/dev/log socket. - -.SH SEE ALSO -.BR mkfs(8), -.BR genromfs(8), -.BR mkisofs(8), -.BR mkfs.jffs2(1) -.br -.SH AUTHOR -This manual page was written by David Kimdon <dwhedon@debian.org>, -for the Debian GNU/Linux system (but may be used by others). -Examples provided by Erik Andersen <andersen@codepoet.org>. |
