New "target is busy" error during latest build attempts

[joejoe44]

On my Debian13 VM that I use to build images for my boards, I have started to notice new errors that I have not seen before after this part of the logs...

 

[🐳|🌱] After updating and cleaning image apt list cache [ 30 files ]
[🐳|🌱] Image installed package hash [ ✅ base-files = 1-trixie-1armbian1-Bb095-U13.8--deb13u4-R55fa ]

[🐳|🌱] Unmounting [ /armbian/.tmp/rootfs-no-uuidgen-yet-15898-49210 ]

 

 

Once the unmounting of rootfs-nouuidgen-yet begins I notice the following errors spam in the logs, 1000+ lines, and finally the target unmounts successfully and the image finishes building. The images still boot fine.

 

umount: /armbian/.tmp/rootfs-no-uuidgen-yet-15898-49210/dev: target is busy.
[🐳|🔨]   tmpfs /armbian/.tmp/rootfs-no-uuidgen-yet-15898-49210/dev tmpfs rw,nosuid,size=65536k,mode=755,inode64 0 0

Is there a way to adjust some kind of timeout for this to prevent the massive amount of "target is busy" outputs in the logs? Thank you for any help or insights!
