install image overflow

[Martin Husemann <martin%duskware.de@localhost>]

Hey,

we are out of space on the install image again:

#    create  install/sysinst.fs
Calculated size of `sysinst.fs.tmp': 1474560 bytes, 400 inodes
Extent size set to 4096
sysinst.fs.tmp: 1.4MB (2880 sectors) block size 4096, fragment size 512
        using 1 cylinder groups of 1.41MB, 360 blks, 416 inodes.
super-block backups (for fsck -b #) at:
 32,nbmakefs: Writing inode 392 (work/./usr/share/keymaps/atari/de.map), bytes 0 + 1279: No space left on device


(the error is slightly hidden in the bulk build results, and a local build
with a short source path works, so it must be pretty tight)

Any ideas what to drop?

Martin
