DetailsNOTE-I opened this task against pacstrap based on the advice in a thread[1] that /usr/bin/mkarchroot does not mount filesystems itself, rather, it does so through a call to pacstrap.
/usr/bin/mkarchroot fails to create a chroot cleanly if I ask it to install just base-devel (see attached log). By contrast, if I ask it to install both base and base-devel, it completes cleanly. Completes fine: sudo mkarchroot /mnt/data/chroot/root base base-devel Ends in error: sudo mkarchroot /mnt/data/chroot/root base-devel Here are the last few lines to demonstrate the error; the complete log is attached: % sudo mkarchroot /mnt/data/chroot/root base-devel ...

As a sanity check, I have every member of the base and base-devel group installed on my workstation. 1. https://bbs.archlinux.org/viewtopic.php?id=168470 Additional info: * package version(s) 11-1 Steps to reproduce: sudo mkarchroot /mnt/data/chroot/root base-devel (see attached log)

I am able to fix this issue by added a sleep step in the api_fs_umount function in /usr/bin/pacstrap. If you inspect the chroot2.log I attached, you will see that after installing 'which' the script sleeps for 5 sec, and then goes on to generate the locales and finish successfully.
Any thoughts?
