Package: lowmem Severity: normal Tags: d-i This is a stange package to file the bug on, since the real bug is in d-i, but mostly people doing lowmem will care about this, and a lowmem hack may be the best/only way to deal with the problem. d-i boots an initrd containing a reduced libc.so, that's about 640k big. During the anna run this is replaced by a fullsize libc. Then d-i goes on and all is well.. except the original libc.so is kept in memory by all the programs that were started up running it (init, cdebconf, etc). I've verified this by checking the /proc/nnn/maps files. Just look for the "(deleted)". During a netinst install, the only such lines by the end of the anna run are for libc.so.6, ld-linux.so, libdl.so.2. I imagine it might be worse if any other libraries are out of sync between the initrd and udebs and get upgraded though. I can't think of a clean way to fix this, but a lowmem hack that forces d-i to restart after anna might be worth coding up, to reclaim this > 640k of memory. -- see shy jo
