New: automount using host mount/umount

Bug ID: 11876
Summary: automount using host mount/umount
Product: buildroot
Version: 2019.02.2
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: todd.valentic at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---

In buildroot, the autofs package is finding the path to the host mount/umount/fsck programs instead of the locations on the target in the autoconf stage. These paths are used by automount and therefore fail to mount when running on the target. You can see the this by looking at the autoconf output puts in config.log or include/config.h for the values of the PATH_MOUNT variables.

The autofs.mk file mentions this problem with modprobe but doesn't set the path for the other programs. The solution is to add the target paths to AUTOFS_CONF_ENV in autofs.mk:

# autofs looks on the build machine for the path of modprobe, so tell
# it explicitly where it will be located on the target.
AUTOFS_CONF_ENV = \
        ac_cv_path_KRB5_CONFIG=no \
        ac_cv_path_MODPROBE=/sbin/modprobe \
+       ac_cv_path_E2FSCK=/usr/sbin/fsck.ext2 \
+       ac_cv_path_E3FSCK=/usr/sbin/fsck.ext3 \
+       ac_cv_path_E4FSCK=/usr/sbin/fsck.ext4 \
+       ac_cv_path_MOUNT_NFS=/usr/sbin/mount.nfs \
+       ac_cv_path_MOUNT=/bin/mount \
+       ac_cv_path_UMOUNT=/bin/umount \
        ac_cv_linux_procfs=yes
