[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0

2020-07-27 Thread Marian Gasparovic
I tested ppa:rafaeldtinoco/lp1861941 several times today on a focal setup where 
it failed 100%. 
Glad to report it passes without issue every single time now.
Thank you

[Touch-packages] [Bug 1861941] Re: bcache by-uuid links disappear after mounting bcache0

2020-07-20 Thread Marian Gasparovic
Just for the record, last week I tried mitigation/workaround as
described in https://paste.ubuntu.com/p/JTB6vYbbkV/ on focal. It failed
exactly the same as without those changes. I reported back to Rafael.
