System: NetBSD carvalho-classic 1.5_ALPHA2 NetBSD 1.5_ALPHA2 (GENERIC) #4: Wed Aug 30 04:29:24 BST 2000 root@dora.int.purplei.com:/files/transient/netbsd/src/sys/arch/sparc/compile/GENERIC sparc


>Description:
When choosing to install from a ftp server, the user is required
to enter the name of a directory containing one or more sets to be
installed.  The question is repeated until the specified directory
is determined to contain at least one of the target sets; this test
is done by obtaining a listing of the target directory via ftp's
"ls" command and matching each line against a set of valid set
names.  However, the behavior of ftp has changed between 1.4.2 and
1.5_ALPHA2; the "ls" command used to send a NLST command and now
sends a LIST command.  The response to a LIST command includes
additional information that prevents the set names from being
matched (possibly as a result of the fix for pr#8937), so it is
not possible to proceed past this question.

>How-To-Repeat:
Install from the miniroot provided in the sparc 1.5_ALPHA2 snapshot;
when asked for the install method, choose "ftp" and attempt to
specify a valid source directory.  "?" will provide a full listing
of the directory (ls -l) showing that the sets exist in the specified
directory, but the request for a remote directory will be repeated;
the only way out is to abort the install with ^C.

>Fix:
/install.sub in the miniroot needs to issue a "nlist" command
instead of a "ls" command to get only the names of the files in
the target directory; with the following change, I was able to
successfully install via ftp.  (In 1.4.2, "dir" and "ls" were
distinct commands, and "nlist" was an alias for "ls"; in 1.5_ALPHA2,
"ls" is documented as an alias for "dir", but "nlist" is documented
as an alias for "ls", which is no longer true)
