| |
Hi all,
As discussed a while ago (see thread starting at http://www.uwsg.iu.edu/hypermail/linux/kernel/0105.2/0659.html), I wrote a frontend to libparted that does nothing but probe all block devices for partition tables, and tells the kernel what partitions it finds. It optionally prints a short summary.
The hope is to be able to remove partition table parsing from the kernel, and share partition table code with libparted.
It's called partprobe, and is distributed with Parted. Get it from:
ftp.gnu.org/gnu/parted/devel/parted-1.5.6-pre2.tar.gz
When partprobe/libparted are compiled with --enable-discover-only --disable-nls etc (see README), it comes to about 73k (35k compressed), not including libc or libuuid. Unfortunately, this is still quite large to be including in things like initramfs. Is it worth paying this price?
libparted currently supports 7 partition table formats (vs 11 in linux 2.4). It uses the blkpg interface in 2.4 to communicate partition info. (see libparted/linux.c, linux_disk_commit)
