Yeah, same happens to me.
I don't use screen anymore, but it occurred to me that this was perhaps if you
changed screen to be setuid root, which seems like a possible security hole, but...

Well, LambdaMOO will let you run it via BSD sockets (or SYSV named pipes)
instead of inet sockets, i don't know about the others...

The extended file system is in alpha right now but is apparently pretty stable.
You can have filenames up to 255 characters in length, and partitions can be about as big
as you'd need at the moment - i can't remember exactly (minix fs partitions can't be more
than 64K blocks).
However, the extfs' performance is rumored to be about 1/3 of minix fs'...
apparently a new version using bitmaps is being developed, which ought to speed things up.

Enjoy !
