Not able to point this db cache location in a flag

[klauern]

What did you do? (required. The issue will be closed when not provided.)

I'm attempting to run the vuls server from a read-only filesystem, using Redis as a backend to store and retrieve all of the information. When I start it up, passing in all of the necessary information to speak to a Redis instance, it fails saying it is unable to fill the Library.

These lines appear to load the Library, with no way to customize it:

vuls/report/report.go

Lines 153 to 155 in d5a3e5c

	nCVEs, err := libmanager.FillLibrary(r)
	if err != nil {
	return xerrors.Errorf("Failed to fill with Library dependency: %w", err)

And the error seems to occur here:

vuls/libmanager/libManager.go

Line 17 in 1fbd516

if err := db.Init(); err != nil {

• Current Output

time="2019-09-20T02:37:19Z" level=error msg="Failed to fill with Library dependency: failed to mkdir: mkdir db: read-only file system" prefix=localhost
