Here is the reason:
Code:
[root@kindle root]# strace -f -F /opt/bin/ipkg list 2>&1|tail
munmap(0x4001b000, 34)                  = 0
close(3)                                = 0
open("/var/local/system/tzVar", O_RDONLY) = -1 ENOENT (No such file or directory)
gettimeofday({1332300008, 690798}, NULL) = 0
getpid()                                = 18936
mkdir("/opt/ipkg-g1rwEY", 0700)         = -1 EROFS (Read-only file system)
write(2, "ipkg_conf_init: Failed to create"..., 85ipkg_conf_init: Failed to create temporary directory `(null)': Read-only file system
) = 85
exit_group(30)                          = ?
Process 18936 detached
[root@kindle root]#
This is harmless, but I do agree that it's annoying. You can either set the environment variable TMPDIR locally or globally (e.g.: )
Code:
TMPDIR=/tmp /opt/bin/ipkg list_installed
TMPDIR=/opt/tmp /opt/bin/ipkg list_installed
For a permanent fix, directly change the default TMPDIR setting inside /opt/lib/libipkg.so.0.0.0 from /opt to /tmp (that's bytes 209c9 through 209cb in the file). I have attached the patched file for convenience.

In either of these cases, it works smoothly with root mounted ro.
