Thanks, I've modified these for my needs.
Unfortunately this doesn't give any significant size drop:
lvm staticly linked with uClibc and device-mapper lib with all features
-rwxr-xr-x 1 misiek users 555815 2004-01-25 21:05 initrd-lvm
lvm staticly linked with uClibc and device-mapper lib using my patch above (so
only vgscan and vgchange functions available)
-rwxr-xr-x 1 root root 482428 2004-01-25 20:51 initrd-lvm
How these sizes look with dietlibc?
Also some problems with lvm way of checking what command user wants based on
argv came out:
[root at arm misiek]# /sbin/initrd-lvm
No such command. Try 'help'.
[root at arm misiek]# ln -s /sbin/initrd-lvm lvm
[root at arm misiek]# ./lvm
Please supply an LVM command.
Available lvm commands:
Use 'lvm help <command>' for more information
help Display help for commands
vgchange Change volume group attributes
vgscan Search for all volume groups
version Display software and driver version information
It would be much better if when argv is not known internally for lvm then
work as argv = lvm.
