Работа с Firefox из tmpfs/Running a persistent Firefox profile from tmpfs
Как известно, Firefox любит насиловать винт во время работы, особенно это касается файлов sessionstore.js, webappsstore.sqlite, places.sqlite и cookies.sqlite.
Я долго на это смотрел, скрипел зубами, не выдержал и написал скрипт, который выкидывает профиль в /tmpfs во время запуска, а потом синкает его обратно.
It's well known that Firefox likes thrashing your HDD when it works. This problem seriously affects these files: sessionstore.js, webappsstore.sqlite, places.sqlite and cookies.sqlite.
To solve this problem I've created a bash script which copies a Firefox profile to a temporary RAM based directory and then, when Firefox finishes, this script copies changed files back to a persistent directory.
Mode of action:
1) Edit: ~/.mozilla/firefox and add
[Profile1]
Name=firefox-tmpfs
IsRelative=1
Path=firefox-tmpfs(if you already have more than one profile, Profile1 should become Profile2,3,4 etc.)
2) Create a directory ~/.mozilla/firefox/firefox-persistent
Within it:
mkdir ad
mkdir bk
mkdir ex
ln -s adblockplus $HOME/.mozilla/firefox/firefox-persistent/ad
ln -s extensions $HOME/.mozilla/firefox/firefox-persistent/ex
ln -s bookmarks $HOME/.mozilla/firefox/firefox-persistent/bk3) Create a symbolic link from /tmp/firefox-tmpfs to ~/.mozilla/firefox/firefox-tmpfs
Create these two files:
$ cat > fxtmpfs.files
addons.sqlite
blocklist.xml
bookmarks.html
cert8.db
chromeappsstore.sqlite
compatibility.ini
content-prefs.sqlite
cookies.sqlite
downloads.sqlite
