I already replied to gdm per mail, but I might as well accnowledge the
bug publically: yes it's a linux bug, and the fix is to get the ALPHA
patches available on nic.funet.fi. Note that the ALPHA-diffs aren't
"official" - they are meant for testing out the keyboard problems and
just happen to contain some other fixes as well (this being one of
them). The file to look for is pub/OS/Linux/PEOPLE/Linux/ALPHA-diff.Z,
which contains patches against 0.99.1.
The alpha diffs also allow running of binaries over NFS (and from a
msdos fs without bmap support), but it's done using the "read" vfs
function, and it doesn't allow page sharing nor demand-loading. Not
recommended for heavy use, but it does work.
