But that's because I know myself and I know if I did it your way I'd confuse the dickens out of myself three days later when finding a usr/, var/, tmp/ inside /home.

The files end up *PHYSICALLY* residing in the /home partition, but *LOGICALLY* on /tmp, /usr and /var. Here's how I implement it. I set up /tmp /usr and /var in /home/bindmounts/ (note the permissions on /home/bindmounts/tmp). [m450][root][~] ll /home/bindmounts/ total 20 drwxr-xr-x 5 root root 4096 Apr 29 13:36 . drwxr-xr-x 7 root root 4096 May 1 00:08 .. drwxrwxrwt 10 root root 4096 May 4 22:00 tmp drwxr-xr-x 15 root root 4096 Apr 29 03:53 usr drwxr-xr-x 14 root root 4096 Apr 28 20:36 var I create *EMPTY* directories named /tmp /usr and /var on /. And then I bind mount the directories. Here's a snippet from /etc/fstab /home/bindmounts/var/varautobind 0 0 /home/bindmounts/usr/usrautobind 0 0 /home/bindmounts/tmp/tmpautobind 0 0 Symlinks would normally work, too. However, if for some reason, the /home partition is unavailable at bootup, the system would complain about symlinks. With empty directories, you at least get a basic system booting up with fewer complaints. Let me repeat the reason for the oddness. The stripped-down / partition is going to be pretty constant, so I don't have to allow lots of empty space as a safety margin. The wildcards, in terms of filespace are... - /var (logs and other stuff) - /usr (/usr/bin for all my apps, and /usr (share, portage, libs)) - /tmp (this is where big temporary files go) -- Walter Dnes [EMAIL PROTECTED] In linux /sbin/init is Job #1 Q.

With the amount of file churn in the tree, the filesystem would get very fragmented very quickly. -- Neil Bothwick I don't know what makes you tick but I wish it was a time bomb. signature.asc Description: PGP signature

RE: [gentoo-user] Re: Reducing disk usage
A bit softer than some of the other suggestions; # eclean packages # eclean distfiles app-portage/gentoolkit contains eclean. From the man page; eclean is small tool to remove obsolete portage sources files and binary packages. Used on a regular basis, it prevents your DISTDIR and PKGDIR directories to infinitely grow, while not deleting files which may still be useful HTH, Adam -- [EMAIL PROTECTED] mailing list
