I've found out how to catch the exception:
(lambda (condition more)
Wouldn't it be better to use errno-error, which hides the Scheme48
exception system, instead of error in uid->user-info and
name->user-info in syscalls.scm? Would such a change break existing
code, e.g. the code in scsh.scm?
Or is there another way to find out if a user/group exists?
