- 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.
