[SOLVED] Archiso temp general question [SOLVED]

I have been messing around now for some time making ISOs to be specific tools....

But have unfortunately run into an issue with the size of the working directory, seemingly being limited to 4GB

Might be FAT related, i have tinkered with, 'mkarchiso' all things 'initcpio' related and anything that relates to 'cow space' and also all the usual '' stuff and all the profile stuff also.

It would i think be a bit exhaustive to put all the configs here, I am probably missing something simple here.

Here are just a few bits from the printouts...

'[mkarchiso] INFO: mkarchiso configuration settings

[mkarchiso] INFO:             Packages File:   /baseline2/packages.x86_64'

'Total Installed Size:  3012.29 MiB'

And failing in the resulting message...

[==================\                                         ] 29900/97568  30%
Write failed because No space left on device

when i examine the tmp work dir it never shows a greater potential capacity than 4gb...

Just to clarify, with a few packages less it works and comes to 700mb iso...

The question being, is this a hard limitation, will i have to just include these extras in the startup scripts or is there some simple thing im missing to create a larger ISO?

I would be very grateful for any insight here

thanks in advance.

Re: [SOLVED] Archiso temp general question [SOLVED]

It may not be an archiso limit.

[mkarchiso] INFO:         Working directory:   /tmp/archiso-tmp2

/tmp is stored in ram and defaults to half your available memory .
See for details and ways to change the amount of space.

You could also try to set working directory to a sdd or hdd drive with more space free then 4 GiB .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
Did you use the guided installer ? If yes, I can't help you.

(A works at time B)  && (time C > time B ) ≠  (A works at time C)

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Jesus christ! Swear I had tried it as non tmp before... Must have been a different config at fault then...

Thanks a bunch lads, taking it out of tmp fixed it!!!

Was choking the ram as it was anyway and im to get some more soon, funding permitted...

I must say, for a first post here its been a great experience, thanks again!
