Under GNU/Linux and *BSD operating systems it is recommended to use 9pfs to mount 9p services.
doas 9pfs -o allow_other 9front /mnt
When using drawterm it is possible to serve a 9P connection directly to the host system
/net and starting exportfs(1) like shown in the script below
#!/bin/rc rfork n bind /mnt/term/net /net aux/listen1 -t tcp!*!12345 /bin/exportfs -r / & os mkdir -p /tmp/drawterm os 9pfs localhost -p 12345 /tmp/drawterm
It requires 9pfs to be installed. A side bonus of doing it this way is, that it uses the drawterm's aan connection to keep the 9p connection up.
The Linux kernel contains a 9p driver that can be made to mostly work with 9front systems. Two things to keep in mind however:
sudo mount -t 9p -o version=9p2000,port=564,trans=tcp your.9p.server /mnt/9p
