Summary: emulators/qemu-user-static: mount(8) cannot show root
filesystem
Product: Ports & Packages
Version: Latest
Hardware: Any

Status: New
Severity: Affects Only Me

Scenario:
- disk903: ZFS volume containing an amd64 FreeBSD head installation
- disk925: ZFS volume containing an armv6 FreeBSD head installation, exported
via iSCSI
- bhyve server running FreeBSD 12.2 (releng/12.2)
- bhyve client running from disk903 -> results in running VM "v903"
- in v903, the disk925 armv6 installation is imported using iSCSI and mounted
on /d/925s2a
- in v903, qemu-user-static is installed
- in v903, a chroot to /d/925s2a is done using
chroot /d/925s2a/ zsh -l
- This results in a shell (zsh) running emulated armv6 binaries.
- (This setup is used to update armv6 ports using portmaster.)
- In this chroot, issue "mount -p /" and "df /".
Result:
[0]# mount -p /
mount: /: unknown special file or file system
[1]# df /
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/diskid/DISK-HAL_V0925s2a 20289716 3970484 14696056 21% /d/925s2a
[0]#
Expected result:
[0]# mount -p /
/dev/diskid/DISK-HAL_V0925s2a /d/925s2a ufs rw 0 0
[0]# df /
