Environment:
System : OpenBSD 6.6
Details : OpenBSD 6.6 (GENERIC) #3: Thu Nov 21 00:59:03 MST 2019

Description:
syspatch adds up the sizes of existing files to be replaced and collects
the device names:
91 stat -qf "_dev=\"\${_dev} %Sd\";
92 local %Sd=\"\${%Sd:+\${%Sd}\+}%Uz\"" ${_files})
\
93 2>/dev/null || _rc=$?
then checks that devices are mounted and are not read-only:
97 for _d in $(printf '%s\n' ${_dev} | sort -u); do
98 mount | grep -v read-only | grep -q "^/dev/${_d} " ||
99 sp_err "Read-only filesystem, aborting"
I have a system with /var and /tmp mounted as mfs. The stat string
format returns '??' for mfs devices:
$ stat -f %Sd /bin/cat
wd0a
$ stat -f %Sd /var/db/libc.tags
??
The 'grep -q ^/dev/??' on line 98 fails causing syspatch to error out
reporting a read-only filesystem, which is not correct.
I noticed this with syspatch66-010_libcauth.tgz which looks to be the
first patch that changes files in /var (like /var/db/libc.tags).

_a_host_:/some/nfs/export on /mnt/_an_nfs_mount_ type nfs (noexec, v3, udp,

Can work around it by modifying the check on line 98. Is it OK to allow
mfs filesystems?
Is the major number for mfs uniquely 255?
$ stat -f %Hd /var/db/libc.tags
255
$ stat -f %Hd /mnt/_an_nfs_mount_
22
