Bug ID: 246760
Summary: ZFS usermount sysrc command invalid
Product: Documentation
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: Documentation
Assignee: [email protected]
Reporter: [email protected]
On https://www.freebsd.org/doc/handbook/zfs-zfs.html under heading 19.4.7.2.
Sending Encrypted Backups over SSH the text says the following.
"To mount the pool, the unprivileged user must own the directory, and regular
users must be allowed to mount file systems. On the receiving system:
# sysctl vfs.usermount=1
vfs.usermount: 0 -> 1
# sysrc -f /etc/sysctl.conf vfs.usermount=1
# zfs create recvpool/backup
# zfs allow -u someuser create,mount,receive recvpool/backup
# chown someuser /recvpool/backup"
When I type the following as using sudo on my 12.1-RELEASE-p2 system I get an
error.
[mike@nas ~]$ sudo sysrc -f /etc/sysctl.conf vfs.usermount=1
sysrc: vfs.usermount: name contains characters not allowed in shell
When I change to the root user I get the same error.
[mike@nas ~]$ sudo -i
root@nas:~ # sysrc -f /etc/sysctl.conf vfs.usermount=1
sysrc: vfs.usermount: name contains characters not allowed in shell
It seems like the valid characters variable in /usr/share/bsdconfig/sysrc.subr
is incorrect.
VALID_VARNAME_CHARS="0-9ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz_"
Should it include a period?
Also, I believe the documentation should clarify when a user needs to run as
root versus when to run as a non-root user. At least it seems like every
command should be run as root but it is not clear.
I had to manually edit the /etc/sysctl.conf file.
