GENROMFS(8) System Manager's Manual GENROMFS(8)NAMEgenromfs - create a romfs imageSYNOPSISgenromfs -f device [ -d source ] [ -V volumename ] [ -a alignment ] [ -A alignment,pattern ] [ -v ]DESCRIPTIONgenromfs is used to create a romfs file system image, usually directly on a block device, or for test purposes, in a plain file. It is the mkfs equivalent of other filesystems. genromfs will scan the current directory and its subdirectories, build a romfs image from the files found, and output it to the file or device you specified.OPTIONS-f output Specifies the file to output the image to. It must be specified. -d source Use the specified directory as the source, not the current directory. -V volumename Build the image with the specified volume name. Currently it is not used by the kernel, but it will be recorded in the image. -a alignment Align regular files to alignment bytes. genromfs will align data of each regular file in the resulting image to the specified alignment, while keeping the image compatible with the original romfs definition (by adding pad bytes between last node before the file and file's header). By default, genromfs will guarantee only an alignment of 16 bytes. -A alignment,pattern Align objects matching shell wildcard pattern to alignment bytes. If one object matches more patterns, then the highest alignment is chosen. Alignment has to be a power of two. Patterns either don't contain any slashes, in which case files matching those pat- terns are matched in all directories, or start with a leading slash, in which case they are matched against absolute paths inside of the romfs filesystem (that is, as if you chrooted into the rom filesystem). -v Verbose operation, genromfs will print every file which are included in the image, along with its offset.EXAMPLESgenromfs -d root -f /dev/fd0 -V 'Secret labs install disk' All files in the root directory will be written to /dev/fd0 as a new romfs filesystem image. genromfs -d root -f /dev/fd0 -A 2048,/.. -A '4096,*.boot' -a 512 -V 'Bootable floppy' Generate the image and place file data of all regular files on 512 bytes boundaries or on 4K boundaries, if they have the .boot extension. Also, align the root directories '..' romfs header on 2K boundary. You can use the generated image (if you have the romfs module loaded, or compiled into the kernel) via: mount -t romfs /dev/fd0 /mntAUTHORThis manual page was initially written by Christoph Lameter <clameter@debian.org>, for the Debian GNU/Linux system.SEE ALSOmkfs(8), mount(8), mkisofs(8) Version 0.3 Sep 1998 GENROMFS(8)
