If / can fit completely on /usr (or vice-versa), then this is easy. 1. Go to single user mode 2. Move everything currently in /usr to 1 lower directory: cd /usr; mkdir usr; mv * usr 3. Copy / to /usr: cd /; find . -xdev -print0 | cpio -pvdm0 /usr 4. At this point, the / partition is redundant, and the old /usr partition has everything. Update lilo and fstab to reflect this. In fstab, remove the entry for /, and rename the entry for /usr to /. In lilo.conf, change the boot partition. vi /usr/etc/lilo.conf vi /usr/etc/fstab chroot /usr lilo -v 5. Reboot, and now / has become the old /usr partition. At this point, you can make a new filesystem on the old / partition, mount it, and copy /usr from the new partition to the old. Go back to single user mode and: mke2fs /dev/hdFOO mount /dev/hdFOO /mnt cd /usr find . -xdev -print0 | cpio -pdvm0 /mnt mv /usr /usr.dontuse mkdir /usr vi /etc/fstab 6. Reboot once more, and if everything looks good, rm -rf /usr.dontuse. MAKE SURE YOU SAVE EVERYTHING IN /etc /var AND /usr/local BEFORE DOING THIS. ALSO MAKE SURE THAT YOU HAVE A WORKING RESCUE DISK. -- Dave Carrigan ([EMAIL PROTECTED]) | Yow! Zippy's brain cells are UNIX-Apache-Perl-Linux-Firewalls-LDAP-C-DNS | straining to bridge synapses...
